Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度,单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力,寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同,包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30,均表明包体与寄主玄武岩浆之间不存在平衡关系,因此,包体是被寄主玄武岩浆捕虏的上地幔碎块。

Now, Sr isotopes can be used not only to constrain the origin and evolution of magma and hydrothermal ore-forming solutions, calculate the scale and degree of lithogenesis and ascertain the relations between fluids and rocks, but also to study sea-level fluctuation, plate movement, ocean-floor spreading and lithogenic evolution.

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

雅山晚阶段黄玉锂云母花岗岩的长石矿物是富磷长石,磷以PAlSi〓替换方式进入长石结构中,并且在长石中的分布很不均一,一般是晚结晶的长石比早结晶的长石的磷含量高,同期结晶的钠长石比钾长石的磷含量高;锆石矿物为高度富铪、铀、磷和铝的锆石,磷主要以(Y, HREE, Fe)〓P〓〓〓Si〓〓、Al〓P〓Si〓〓、P〓Al〓Si〓〓Zr〓〓等替换方式进入锆石晶格中,富磷锆石是岩浆高度演化的结果,是高磷花岗岩的特征矿物之一;雅山含有丰富的磷锂铝石,是高磷花岗岩的主要磷酸盐矿物;铌—钽矿物主要有铌锰矿—钽锰矿、锡锰钽矿—钛锰钽矿、细晶石等。

Bassed on many kinds of characteristics of the alkaligranite, the paper establishes a complex genetic model of A-type granite in wulungu alkali-granite, that is" activity of mantal material+partial melting of hydrous-absent saclic source rock+differentiation of granitoid magma+tensional geological envioment".
